Viewing Past Lectures

Video recordings are currently made of all Colloquium Lectures, and many of the past lectures were also recorded (DVD, VHS, Beta, or audio cassette). These recordings can be borrowed, by employees and contractors of NASA Langley Research Center only, from Langley’s Technical Library (x42356). Since December 2013, online versions of the lectures are also made available within the NASA Langley firewall. Additional past lectures are being added to this collection as time permits. The Colloquium Committee is not responsible for the choice of which lectures to include in the on-line collection.

A list of past colloquium lectures is available to help you select which lectures you’d like to catch up on. Note that these lectures are the intellectual property of the individual speakers and may not be copied, distributed, or used for any purpose other than personal viewing.
